Aneurin "Nye" Bevan PC was a Welsh Labour Party politician, noted for tenure as Minister of Health in Clement Attlee's government in which he spearheaded the creation of the British National Health Service. He is also known for his wider contribution to the founding of the British welfare state. He was first elected as MP for Ebbw Vale in 1929, and used his Parliamentary platform to make a number of influential criticisms of Winston Churchill and his government during the Second World War. Before entering Parliament, Bevan was involved in miners' union politics and was a leading figure in the 1926 general strike. Bevan is widely regarded as one of the most influential left-wing politicians in British history.

The Labour Party is a political party in the United Kingdom that has been described as an alliance of social democrats, democratic socialists, and trade unionists. The Labour Party sits on the centre-left of the political spectrum. In all general elections since 1922, Labour has been either the governing party or the Official Opposition. There have been six Labour prime ministers and thirteen Labour ministries. Since the 2010 general election, it has been the second-largest UK political party by the number of votes cast, behind the Conservative Party and ahead of the Liberal Democrats. The party holds the annual Labour Party Conference.
